Hi, is there a possibility (parameter in dts file) to get the mclk from the sitara and not from an external oscillator? With external clock it works fine now. BR, Kai

[alsa-devel] [PATCH] ASoC: nau8825: Disable short Frame Sync detection logic
by John Hsu 11 Nov '16

11 Nov '16

If the short Frame Sync detection logic enabled, the logic will check the short frame sync threshold. If frame sync is less than the setting; for example, frame sync less than 252 MCLK, the short frame sync signal is flagged, digital filter temporary mute and skip that data. If the system was intended for sampling rate change which could create temporary short frame sync and not enough MIPS to run the digital filter. But the situation doesn't happen in ALSA architecure. Thus the Frame Sync is always stable, then no require to do the detection. Therefore, the dirver disables the function for better performance.

[alsa-devel] [PATCH 00/30] Modernize documents
by Takashi Iwai 10 Nov '16

10 Nov '16

Hi, this is a patch set to convert most of document files in Documentation/sound/alsa/ and Documentation/DocBook/ to the ReST format that has been recently introduced. The files are moved to a few different subdirectories depending on the contents, with renames to lower letters to be more consistent. I didn't try to correct / update the contents unless really needed, but only concentrate on reformatting. Most of changes are trivial, and can be seen easily in git diff. Some are more intrusive (e.g. the conversion from DocBook or HTML). The ASoC documents aren't included in this patch set. They will follow later. The latest changes are found in topic/restize-docs branch of my sound git tree.

The core expects "const char * const" and "unsigned int" for enum controls, the mixer control definitions in wm2200 use "const char *" and "int". This patch corrects the type of these arrays.

[alsa-devel] [PATCH 1/2] ASoC: arizona: Move notifier functions to header and make inline

These functions are very thin wrappers around core functions, so they make sense as inline functions. Also making them inline avoids build issues in the case where the machine driver is built in but the CODEC is built as a module.
